Wenzhounese , also known as Oujiang or Dong'ou (東甌), is the speech of Wenzhou, the southern prefecture of Zhejiang Province, China. Nicknamed the "Devil's Language" for its complexity and difficulty, it is the most divergent division of Wu Chinese, and is sometimes considered a separate language. It features noticeable elements of Min, which borders it to the south. Oujiang is sometimes used as the broad umbrella term, reserving Wenzhou for Wenzhounese proper in sensu stricto.
